Breaking changes

Features

#76 Implement ToBytesGadget for Vec<UInt8>.

Improvements

Bug Fixes

#77 Fix BLS12 G2PreparedGadget's AllocVar when G2 uses a divisive twist.

v0.3.1

Features

#71 Implement the Sum trait for FpVar.
#75 Introduce mul_by_inverse_unchecked for FieldVar. This accompanies the bug fix in #70.

Bug Fixes

#70 Fix soundness issues of mul_by_inverse for field gadgets.

v0.3.0

Breaking changes

#60 Rename AllocatedBit to AllocatedBool for consistency with the Boolean variable. You can update downstream usage with grep -rl 'AllocatedBit' . | xargs env LANG=C env LC_CTYPE=C sed -i '' 's/AllocatedBit/AllocatedBool/g'.
#65 Rename Radix2Domain in r1cs-std to Radix2DomainVar.

Features

#53 Add univariate evaluation domain and Lagrange interpolation.

Improvements

#65 Add support for non-constant coset offset in Radix2DomainVar.

Bug Fixes

v0.2.0

Breaking changes

#12 Make the output of the ToBitsGadget impl for FpVar fixed-size
#48 Add Clone trait bound to CondSelectGadget.

Features

#21 Add UInt128
#50 Add DensePolynomialVar

Improvements

#5 Speedup BLS-12 pairing
#13 Add ToConstraintFieldGadget to ProjectiveVar
#15, #16 Allow cs to be None when converting a Montgomery point into a Twisted Edwards point
#20 Add CondSelectGadget impl for UInts
#22 Reduce density of three_bit_cond_neg_lookup
#23 Reduce allocations in UInts
#33 Speedup scalar multiplication by a constant
#35 Construct a FpVar from bits
#36 Implement ToConstraintFieldGadget for Vec<Uint8>
#40, #43 Faster scalar multiplication for Short Weierstrass curves by relying on affine formulae
#46 Add mux gadget as an auto-impl in CondSelectGadget to support random access of an array

Bug fixes

#8 Fix bug in three_bit_cond_neg_lookup when using a constant lookup bit
#9 Fix bug in short_weierstrass::ProjectiveVar::to_affine
#29 Fix to_non_unique_bytes for BLS12::G1Prepared
#34 Fix mul_by_inverse for constants
#42 Fix regression in mul_by_inverse constraint count
#47 Compile with panic='abort' in release mode, for safety of the library across FFI boundaries
#57 Clean up UInt docs

v0.1.0
